I especially like what they do for musical timing. Biggest bang for buck is under my Sonneteer CD player.

Very rarely do they come up for sale used. Believe me I keep looking for more! When they do appear, it's generally someone upgrading to the new ones, or the big ones.

Some of the BR posts seem to have not been moved across so rather than continue this on the fuse thread I've brought it up here.

I accept there have been a few replies to this post but I'd still like to understand where the statement about minimising electrical output came from.

Ok thank you.

I admit I haven't read every post in that thread but to answer my own question it would appear to be just a continuation of speculation. The first mention of this was about three years ago and yet the manufacturer still doersn't make this claim...

No.  I wonder if they're just using a phrase familiar to audiophiles?  It seems sloppy to me because I think of burn-in as an electrical property.

For me, they take a little settling the first time you use them and then the weight achieves ideal compression over a few hours.  After that, they just do the job of making the component resting on them sound better.

I use original Black Ravioli under my pre and power amps and the difference it makes is obvious right from the start. Even more so with the lastest model which I heard when Martin brought his over. I am looking forward to adding them in the future to all my kit.

Some left over stuff, packing materials and the like
Bubble wrap maybe. Polystyrene or foam of some sort.
Best VFM is either RDC cones or Electric Beach.
Make your own wooden or similar cones.
Cheapo sorbothane

For cheap isolation, you can always pick up an old mission/Cyrus Isoplat for £15-20. They don't age well though, so you may need to respray it. They do make a difference and look good too, when tarted up.

For DIY I'd say making your own version of a "Silentstage" is a good move. It works with vinyl and CD and looks great. You need to order 2 sheets of 15mm thick acrylic from a large eBay seller. They will cut and flame polish the edges. Use 4 blobs of Blu-tack or similar to separate them and whack four "Foculpods" on the bottom. I made one of these and it had a very worthwhile effect with many turntables and CD players.

Others swear by IKEA bamboo chopping boards but I haven't tried them.

If you are into DIY you can always use anti vibration mounts. Roksan used these on Xerxes and TMS .

I also use this stuff whilst I await more Black Ravioli coming up for sale used.

It looks ordinary from the outside, inside is a complicated construction of many different materials (Derrick the inventor told me this)

It beds in once the weight of the component settles on it.

Its priced very well for what it does, much better than other brands I could mention in my personal experience of using them all.

Quite a few people came to see me at the show just gone in Bristol, I got back at 11.30 last night then was in at work at 7.30 to un-load so all the stock could be put back to send orders out.

Anyway almost everyone who picked a BR pad up said whats in it, true Yorkshireman reply on my part, who cares whats in it if it works.

If you can afford it try it, if not just carry on taking the p..ss out of it that's fine. Its made in Scotland from girders, that's all I need to know.
